GRAIN BINDER Filed Oct. 20, 1930 2 Sheets-Sheet 2 Patented Nov. 17, 1931 UNITED STATES PATENT ()FFICE GUsrAr orxcHIcAGo, ILLINOIS, ASSIGNOR r INTERNATIONAL rmavnsrnn COMPANY, A'ooRroaATIoN or NEW messy GRAIN BINDER The invention relates to improvements in grain binders. f

These machines embody a grain binding deck with which :is associated va butter to line up :the' butt ends of the grain, so that better bundles will result. It i's'found that with present constructions of harvesters the butter is .difiicult to support and, as a result, objectionable sagging of the butter develops, which makes it diflicult properly to operate the same. 7 1.

Accordingly, the invention more specifically relates to animproved butter construction for agrain harvester.

The objectsof the invention are to provide an improved supporting means for the butter and generally to improve the operation there of by preventingobjectionable sagging.

These desirable objects may "be achieved by the structure illustrated in "the accompanyingdrawings, in' which: r

Figure 1' is a front velevational View 0 so much of agrain binder as is necessary to illustrate theinvention; and

Figure2 is a plan view of the structure shown in Figure 1.

A part of a grainbinder frame is-shown at carrying a bracket 11, to whichis connected the elevator 12, in the-upper end of which isjournaled the usual conveyor drive shaft 13 carrying, in-the usual manner, the bevel gear 14 which drives a bevel gear 15 carried at the lower end ofa crank shaft 16, suitably; supported on the bracket 11 and frame piece 10. The bracket 11 has connected to it a downwardly-inclined lower binder deck .17. At the lower end of the binder deck, the frame o-fthe binder carries the usual binder frame 18 the upper end of which is provided with a'bracket 19.

The upper end of the crank 16 carries a sleeve'20, which sleeve includes a bifurcated extension 21 secured to a butter board 22 carrying the usual butt engaging elements 23. The outer end of said board 22 carries a bracket 24, in which is carried a shaft 25 connected by a cross brace-26 includingbearings 27, in which is journaled a cranked outer end 28 of a supporting shaft 29, which has its inner end bent downwardly, as at 30, and carried in suitable bearings 31 in the bracketll. The shaft 25 pivotally carries a butter boa-rd extension 32, the front outer face of which carries a slotted bracket 33, through which slides a strip 34 connected by a bifurcated bracket 35 to the shaft 28.

The upper end of the bracket 11 carries an extension 36, and a brace rod 37 is connected between said bracket 36 and the bracket 19 in a manner to support the, outer 160 end of thebinder frame 18. The upper end of the bracket 11 also carries a slotted bracket 38, through which is passed a push and pull bar 39 having a handle 40 accessible to the operator on his seat, which bar 39 is connect- :i

ed to an angle bar continuation 41 that is bent downwardly, as at 42, and made fast,

as at 43, to the bifurcated bracket 35 heretofore described. By pulling or pushing on the handle 40, the operator can move the' butter mechanism forwardly or backwardly with respect to the grain deck 17, properly to set the butter in accordance with varying lengths ofgrain being handled. The upper binder deck is conventionally supported and appears at 44.

So much of the structure described is standard practice in the grain binder art, and'here it will be seen that the weight of the butter mechanism is carried by the crank' shaft 29 and the adjusting bars 39, 41. It is found that by such inadequate supports the'butter eventually sags and in operation drags acrcssthe binder deck 17. which scriously interferes with its proper function. Ac-

cordingly, this invention provides additional supporting means for the'butter mechanism, which will now be described.

A bail member 45 has'one leg 46 connected at 43 to the downward extension 42 of and, as a result, adjustment of the butter can more easily be effected. To provide a better sliding action of the adjusting bar 39, a slide shoe 49 is provided underneath the bar 41, as shown in Figure 1, so that the shoe 49 will slide across the top of the upper binder deck 44.

In operation, the gearing 14, 15 causes the crank 16 to turn and impart to the board 22 an orbital movement. which is communicated to the extension 32, while the crank 28 merely serves as a swinging support for the parts. This swinging support is relieved of most of its supporting duty by the improved support 45 described, which is hung from the supporting brace 37 and, because of this construction, the shifting rod 39 is also relieved of supporting duty and can, therefore, be more easily manipulated for adj ustably setting the butter board mechanism.

From this detailed description, it must now be apparent that an improved construction has been provided, which achieves all of the desirable objects heretofore recited.

The illustrative example herein chosen for purposes of disclosure is obviously susceptible of changes and modifications without departing from the spirit and scope of the invention as expressed in the following claims.

What is claimed is:

1. In a grain binder a main frame, a binder deck carried thereby, a brace extending above said deck, a butter extending across the deck, means for supporting and driving the butter, means connected to the butter for setting the butter in various positions of adjustment relative to the deck, and means suspended from the brace providing an additional support for the butter.

2. In a grain binder, a mainframe, a binder deck carried thereby, a brace extending above said deck, a butter extending across the deck, means for supporting and driving the butter, means connected to the butter for setting the butter in various positions of adustment relative to the deck, and means suspended from the brace and having sliding movement relative thereto providing an additional support for the butter.

3. In a grain binder, a main frame, a binder deck carried thereby, a binder frame, a brace connected between the main and binder frames extending above said deck, a butter extending across the deck, means for supporting and driving the butter, means connected to the butter for setting the butter in various positions of adjustment relative to the deck, and means suspended from the brace providing an additional support for the butter.

4. In a grain binder, a main frame, a binder deck carried thereby, a brace extending above said deck, a butter extending across the deck, means for supporting and driving the butter, means comprising a bar connected to the butter for setting the butter in various positions of adjustment relative to the deck, and means suspended from the brace and connected to said bar providing an additional support for the butter.
